branchlets angular; leaves ovate, ovato-lanceolate or oblong, cuneate or rounded at base, acute; peduncles 1–3, axillary, leafless (or branched and leaf bearing); upper and lateral calyx-teeth triangular-acuminate, lowest setaceo-subulate, rather shorter than the rest; keel thrice as long as the calyx tube; pod scarcely winged. Very similar to R. triflora, but with more acute, more lance-shaped leaves; more isosceles-triangled upper calyx-teeth, and a longer and more rostrate vexillum. I retain the species with much doubt. Dr. Pappe (No. 58), unites it to R. triflora.
